At present, China's microfinance institutions develop fast and well, but there is information asymmetry between the microfinance institutions and investors, borrowers as well as donors, which goes against the long-term development of the industry. The establishment of microfinance institutions rating can fully solve such a problem. Based on the introduction of the current situation of the development of our country's microfinance institutions, we carry on the analysis of the necessity and development opportunities of constructing our country's microfinance institutions rating.
